Letters Patent No. 101,5'73, dated April 12, 18,70; antedated April7,1870.

IMPROVEMENT IN IMPLEMENT.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, W. A. SHARP, of TamaCity, in the county of Tama and State of Iowa, have invented an ImprovedCombination Tool; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being bad to theaccompanying drawings forming part of this specification.

The object of this invention is to combine in one tool under aconvenient arrangement, a number of tools, such as are used byhouse-joiners, several of which are especially adapted forweather-boarding, but including, also, implements useful for otherpurposes.

The invention comprises the combination in one tool of a siding-hook orgauge, level, plumb, compass, calipers, try-square, bevel, foot-rule,edging-plane, rabbet-plane, screw-driver, tape-measure, andmarking-gauge.

Figure 1 represents a front side view of my improved tool.

Figure 2 represents a rear side view.

Figure 3 represents an edge view.

Figure 4 a transverse section; and

Figure 5 a detail.

A represents a block of wood, preferably twelve inches in length, and ofany suitable width and thickness, covered with smooth brass, copper, orother plates, the one on the side B being wider than the block, andprojecting at the' edge E beyond it.

Both side-plates are provided with scales of inches and fractionsthereof, as shown at D D.

The front side is also provided with an inch scale, beginning at E, andmarked with figures as high as six. Between the three and six inch markson this scale a slot, F, is made, and a gauge-plate, G, adjust- Q thepoints that is required for the parts of the boards exposed to theweather, and placed against the lower edge of the board last nailed on,and the other point pressed into the board near the top, where a nailmay be temporarily driven, so as to support the lower edge of the boardtill secured by a nailing.

At K I have placed a compass in a recess in the stock, and at L aspirit-level, at right angles with the edges, to indicate vertical orplumb lines.

In the end opposite,M represents a tape-measure and reel. f

N is a plane-iron secured in a suitable seat at the edge overlapped bythe side-plate B, and secured by a wedge, O, driven laterally.

This plane serves as an edging-plane for narrow stuff, and arabbit-plane on wider stuff. A 1ng,P, projects-from one side of thisplane, iron for tapping with a hammer for driving it in or out.

Q represents a long slot in the front side of the stock; and

'R a narrow one on the opposite side, wherein a marking-gauge, or knifeS, works, the shank T of which is provided with a spiral spring arrangedto keep the point above the surface of the lower side of the stock, whennot required for use; it is forced down when being used. I

This gauge is designed for marking the siding for cutting off forfitting the ends to the corner boards,

window-flames, gables, 850., and the gauge-plates U and V are providedfor use in connection with it.

The plate U is provided with a proj ection, W, which, in connection withthe gauge-plate V, serves, by being placed against the edge of thecorner board, or window-frame, or gable-end boards, to hold thestock atthe proper point across the piece of siding for the mark to be made bythe marker S, coincident with the edge ofthe boards, by which mark theboards may be cut to fit.

For marking off the boards for any required bevel,

or to mark for sawing miters, the gauge U alone is used. The straightpart X being placed against the edge of the board, a hole, as, isprovided for removing the knife-for sharpening. The head of the shankscrews oil for this purpose.

Y represents a tongue, pivoted at Z, between one of the side-plates andthe block, and arranged to shut in between the same, and to be openedoutward for use as a bevel. It may, also, be drawn out perpendicular tothe stock, and then shoved back, the end being slotted (as shown indotted lines) so as to be held between the rivet and end-plate of thestock, rigidly, for use as a try square.

A represents a screw-driver with a projecting head, B, and provided witha scale, 0. This is arranged to slide in and out of a recess at one endof the stock, and serves, also, for use as calipers.

D representsthe spirit-level in the edge, whereby the stock may be usedas an ordinary level.

It will be seen that any one of these several instrnments-may be madeuse of without being interfered with by the others.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combined tool consisting essentially of the spirit-level L,try-square, bevel, siding-gauge S T, footrule D, plane N, andmarking-gauges, all arranged upon the stock A, substantially at hereinshown and described.

W. A. SHARP.
